Usage guidelines
In most cases, the default settings are sufficient. You can edit the timers, depending on the network
conditions.
•
In a low-speed network, increase the client timeout timer.
•
In a vulnerable network, set the quiet timer to a high value.
•
In a high-performance network with quick authentication response, set the quiet timer to a low
value.
•
In a network with authentication servers of different performance, adjust the server timeout
timer.
The network device uses the following 802.1X timers:
•
EAD rule timer (ead-timeout)—Sets the lifetime of each EAD rule. When the timer expires or
the user passes authentication, the rule is removed. If users fail to download the EAD client or
fail to pass authentication within the timer, they must reconnect to the network to access the
free IP.
•
Handshake timer (handshake-period)—Sets the interval at which the access device sends
client handshake requests to check the online status of a client that has passed authentication.
If the device does not receive a response after sending the maximum number of handshake
requests, it considers that the client has logged off.
•
Quiet timer (quiet-period)—Starts when a client fails authentication. The access device must
wait the time period before it can process the authentication attempts from the client.
